The latest investor call from Funcom reveals revenue for Q4 2013 is down from last year's $7.78 million in the same period, to $4.27 million this year. Deferred billings, weaker sales and competition are cited.

However their big MMO projects are "relatively stable" with Age of Conan and Anarchy Online their primary revenue. All their MMOs are providing a "cash flow positive".

Age of Conan is celebrating its 5th anniversary with a wave of huge monsters terrorising the MMO world of Hyboria. Beginning tomorrow at 4.00pm CET/10.00am EST there'll be huge boss monsters for five days.

Great rewards are teased for those strong enough to take them down. Funcom are also doubling up XP boosts and Bonus Points to spend in-game, and Access Passes to the Khitai region.
